CHANGE-MAKING AND COMPUTING MACHINE;

1% it known that I, ROBERT L. BAI EY, a

"citizen of the United States, residing at- Portland, in the county of Multnomah and State of Oregomhave invented certain new vand useful Improvements in Change-Malt ing and Computing Machines, of which the .following is a specification.

I to 20 This invention embodies a 'machine designed particularly for use in establishments where money is handled in large quantities, such as mercantile establishments and stores generally, factories, and the like, the purpose of the machine being to automatically compute and deliver change. I

The present machine is especially useful in establishments where money is tendered in'payment for purchases, and it is necessary calculate the difl'erence between the amount of a purchase and the amounttendered, such difference representing the amount of change due a purchaser and which will be delivered to him in the operation of the machine herein descril ed.

-T his invention relates to money handling broadly, however, and comprises a machine capable of use for selecting and delivering change either with, or without the operation ofautomatic computing or predetermining means, involving a subtracting action, as above premised, and including certain novel features of construction set forth in United States Letters Patent No. 985,136, issued to Thomas Bilyeu and William S. Overlin.

-\Vl1ile the present invention, as described in detail hereinafter, may be used alone as a computing machine. it is contemplated to associate therewith any well known type of registering, indicating, and printing or recording devices, many of the latter of which are in common use today on cash registers, adding and similar machines. Such combinations of mechanisms would depend'on the particular purposes or uses to which a ma chine of this class is put. I

In carrying out the invention. it is contemplated to employ suitable receptacles for coins. or, in the event paper currency is to he handled by the machine. money holders capable oi' reccivmgor delivering such currcncy would be employed, peculiar selecting Specification of Letters Patent.

Application filed November 1, 1912.- Serial No. 729,093.

selector mechanism is proposed in the pres- 7 cnt invention to effect an' elimination of selected ejectors. or in other words, it will render the delivery devices set in an operative position inoperative, thus performing what may'be called the subtracting op eration hercinbetore referred to. Said re; adjustment, however, is not confined to the performance of a subtracting operation but may reside in the re-arrangement of the selector and delivery means, whereby the ultimate automatic computing action would involve addition or other arithmetical opera-- tions. I

Still another present machine resides in the special means employed whereby, when one. of the selector or delivery mechanisms has been set for operation, a certain portion of said mechaimportant feature of the nism may subsequently be rendered inoperv ative and another portion permitted-to remain undisturbed, and still another portion caused to be thrown from an inoperative to an operativeposition. It is by the instrull'ltiltflllilOS fOl' accomplishing the above that the special computing action is obtained for facilitating handling to best advantage of change elements of different denominations, as will be more fully disclosed hereinafter.

With the above and otherobjects in view,

a full comprehension of the details of con-' struction of this invention will be obtained hysreterence to the following description and to the accompanying drawings, in which Figure 1 IS a plan view of a machine embodying the invention with the com receptacles removed, and a part of the top cover plate broken away to show the interior mechanism. Fig. 2 is a front elevation of the same with the front wall broken away. Fig. 3 is a sectional view taken about on the line 33 of Fig. Fig. 4 is an end elevation of the machine with the end wall removed and rock shaft in section. Fig. 5 is a perspective view showing more clearly the peculiari ties in the arrangementand construction of the selector mechanism, the manipulative devices coact-ing therewith and the intermediate connections.

Throughout the following detail descrip tion and on the several figures of the drawings, similar parts are referred to by like reference characters.

While the present machine, as herein dc scribed, and as illustrated, is adapted for making change in one and five dollar units from one to ten dollars inclusive, and for computing and paying the difference in change between any two given amounts within the limits mentioned, it will be understood that the principle of operation of said machine may be carried out in the provision of a machine adapted for performing the functions described in handling coin or money of practically all denominations, a duplication of the parts merely being involved in accomplishing the desired result.

Generally speaking, the present invention involves certain details and arrangement of parts heretofore well known in this art in their broad aspect and certain of winch are shown in the patent hereinbefore men-,

tioned.

.In the drawings, suitable coin receptacles are designated A, B, O aml l), the receptacle A being adapted to contain one dollar pieces to be delivered one at a time; B and (1, one dollar pieces to be delivered either one or two at a time, and I), live dollar pieces to be delivered one at a time. Cooperating with the said receptacles is delivery means comprising ejector mechanism and cooperating selector means.- The ejector mechanism may be constructed so as to be used in connection with coin rmzcptaclcs such as above referred to or for operation of money holders such as might be employed when paper currency is used in a machine of this type.

The ejector mechanism comprises cjcctors E, E E E", E and It, the same being associated with the coin receptacles A to l) inclusive, and having one end arranged to deliver or ejcct a coin or coins from the lower end .of said receptacles. the other end of each cjcctor being formed with a downwardly extending lug t. A plurality of lock nicml'icrs 3 arc arranged adjacent to the inner ends of the cjcctol's aforesaid, and are formed with posite'sidcs of each ejector normal positions of the that the lugs thereof and its lug 1. the

are seated in the rethelr ejecting movement.

locking recesses at opcjcctors being such cesses of the member 3 at one side of the arms F of a main actuator comprising the rock shaft (l and the operating handle ii, the arms F projecting from said rock shait and extending at their upper ends between adjacent recesses of the lock members 3. The arms F have at their upper ends notches F into engagement with which the lugs 1 of the cjectors are adapted to be moved by a bodily movement of the inner ends of the ejectors in the same plane as Obviously, when the lug 1 of an ejector has been disengaged from a locking recess of a cooperating member 23, it may be moved into engagement with the notch F of the adjacent arm F and thus arranged so that, on operation of the actuator G, the ejector will be operated. The arrangement of the recesses of the members 3, however, is such that the e ectors are adapted to be moved so that the lugs 1 may not only be drawn into engagement with the notches F", but may receive a further movement in the same direction so as to pass entirely through said notches F into engagementwith recesses opposite those in which said lugs 1 normally rest. The recesses of the members 3 are therefore adapted to lock the ejectors from movement when the latter are positioned inoperatively on either of opposite sides of the arms F. The extent of movement of the arms F is shown by dotted lines at F in Fig. 3, and such movement, of course ejects coins from those coin receptacles, the ejectors of which have been previously selected or rendered operative.

Beneath the cjectors E to E", inclusive, and arranged transversely relative thereto, are yokes Y pivotally mounted at Z and the upper portions of which are provided with projections 11 that enter slots 12 in the ejectors. By pivotal movement of the yokes Y, one or more of thc ejectors E to E, inclusivc, is adapted to bc movedlaterall at its inner end into cngagcmcnt with a notch F" of an adjacent arm I" or into a recess of a member 3 opposite that recess with which said cjcctor is normally engaged. The yokcs form members of selector means for the said cjcctors. and springs 10 engage. the yokcs so as to normally hold the cjcctors in their normal inoju'rativc positions. The selector means comprchends indcju'ndcntly operable manipulative dcviccs comprising scparativc series of keys designated 1 and \V. The keys 7: and w are numbered from I to 10. inclusive. and each comprises a stem suitably mounted for vertical movement in the casing of the machine. The keys of the series l are so munbcrcd that any given key indicates the amount of money con-i trolled by it for the purpose of delivery from the machinm Said scrics P of keys are operated according to the amount of .inoney tendered by a purchaser, in so far as the relation of this series of keys to the series W is concerned. The series W of keys areoperated according to the amount of a purchase or sale, or an amount which is to be deducted from that previously selected by a key of the series P. The manlpulative devices P and W are so arranged and con- 'shaft 7, said levers'having' operative connection at 8 with selectors S and R, which are slidablehorizontally in transverse guides 9,.the latter selectors. For thepurpose of more clearly undere standing the peculiar action of the various H selectors, the same will be divided into; classes, those designated S comprising a' main selector mechanism cooperating with the keys. of the series P, and those designated R comprising an auxiliary selector mechanism which includes primary and secondary selectors.

The various selectors are provided with lugs-on their upper edges to engage with the yokes Y for shifting the latter and thereby placing predetermined ejectors in operative position. The selectors are adapted to movea given distance horizontally upon actuation of the manipulative devices cotiperating therewith, but only onehalf-of said horizontal movement is required to move a yoke Y a'sufiicient distance to place its associated ejector in operative engagement with an ejector arm 4. The yoke actuating lugs L of the selectors S comprise ing' the main selector mechanism are there fore soarranged that one-half of their horizontal movement is accomplishedbefore engagement is had with the yokes Y, the latter half of their movement causing the ejector-s cooperating therewith to be placed "in delivery position, such position being shown by dotted lines A and A in Fig. 1. ,In F ig, 2, it will be observed that certain lugs V of the selectors It included in the auxiliary selector mechanism, are'in engagement with the yokes-Y when the latter are in their normal positions, so obviously, if a key of the series \V be depressed the entire horizontal movement of its associated selector R will be transmitted 'to cooperating yokes Y and the ejectors connected with said yokes will pass from the. normal inoperative position to a similar inoperative being notched to receive the position on. the opposite side of the ejector arms which causes the lugs l of said egectors to. move from one of the locking recesses ofa member 3 to an opposite locking recess; Describing the operation of the main and auxiliary selector mechanisms in detail and referring particularly to the specific referenee designations on Fig. 5, the main selector i S is provided with two lugs L and will be operated by depression of key (i of ser es P so as to be moved into dotted line position,

' shown in said figure, the lugs L causing their respective yokes Y to move the associated ejectors E and 'E into deliverypositionsj so that it the handle H'is turned, saidejectors will deliver asilver dollar-and a five dollar gold piece from the machine into the chute M. Should the key 6 'ofthe series .W be depressed before the actuator G is operated, as above described, the auxiliary selector R connected to thelast mentionedkey will engage the yokes Y previously operated by the main selector S, and move said yokes to place their cooperating 1 ejectors in a second or lnoperative posltlon 9.0

sot at the actuator, if operated, will not effect a delivery of any money since the auxiliary selector'lit has lugstV that are adaptedto cooperate with the same yokes as the lugs L. The auxiliary selectorslt. having the direct coiiperation. 1n the manner above described, are termed herein primary selectors todistinguish them from the secondary selectors later to be described.

The transaction above described is the subtraction of six dollars from six dollars, and

w the subtraction of one dollar from six dollars the denominational selecting action oi the main and auxlliary selectors is made necessary, and the present invention accomplishes this by simple effective means, now tobe de- S(.'l'll)0(l,

As an example, the action of the parts in the operation of subtracting three dollars from six or seven dollars will be set forth, andstill referring to Fig. 5, it will be seen that the main selector S" associated with the key stem 3 of the series I is provided with threc'lugs L" for the selection of'three one-dollar se lcctors E E and E". Associated with the main selector S is an auxiliary selector mechanism comprising a primary selector Ti and secondary selectors IF" and R The primary selector R is designed for (lirect cooperation with the ejectors, as described in reference to the selector R". In vother words, said primary selector R is connected with the key stem 3 of the key designated 3 of series W so that, if three dollars is initially selected, by operation of key 3 of series 1, said three dollars may be directly eliminated for a subtraction operation by actuation of the key 3' of series W. In'subtracting three dollars from six dollars, the initial depression of the key (S-of series I not only moves the selector S to place the ejector-s15 and F. in an operative position, but the lower end of the key (3 of series 1 engages and de )resses an arm 15) of shaft 20, said shaft 20 iavin" an arm 21 connected by links 22 and 23 with bell cranks I, the upper arms of which carry lateral pins engaging the lower portion of the secondary selector R. The bell eranksl are mounted on the shafts l7 and on said shafts are'mounted also two bell cranks 15 cooperating with the primary selector R the cranks 15 having arms 24. in the path of movement of the cranks I and normally holding the app arms of the cranks I depressed by reason of the provision of springs 16 connected to said arms 24. The springs 16 hold the upper arms of the cranks 15 elevated.

The secondary selector ll adjacent to the selector R is also in cooperation with parts I and links 22 and '23 equivalent to those above described, the link 2'2, however, being connected to an arm 21" on a shaft 21" having another arm 21" operable by the key T of series I in the same manner as arm 1.) is operable. oy thekey (3 of said series. The main selector S is therefore associated with the primaryselector IF and the secondary selector R said selectors R R and 11 being connected by a pin 13 which passes through vertical slots 14 in corresponding ends of said selectors. The pin 13 passes through a bar R directly connected to the lever (i which is operated by the key StGIlTi'i'. By reason of the connection lit-14, the selectors it R and h are adapted for simultaneous longitudinal movement and independent vertical movement and the bell cranks 15 normally holding the selector 11 elevated, operate rcversely to the cranks I which normally support the selectors 1 and R in their lowermost positions, the range of relative vertical movement of the parts R 2, R and R being shown in Figs 2 am 0.

Now reverting, on depression of the key 6.

of series I, the movement of the parts 19, 21, 22, 23, 15 and I, is such that the selector R which is normally in the same horizontal plane as the selector S, is lowered into an inoperative position and the selector R is elevated by its cranks I into a position in the same horizontal plane as said selector S.

Theseleetor S has threelugs L to select three one-dollar pieces, whereas the selector has three lugs, two of which, designated V' are adapted to select two oue-dollar pieces andthe other of which, V is adapted to engage and render iI101)LiItl\'L. the selector E for the five-dollar pieces. Thus, the depression of key (3 selecting a one-dollar piece and a five-dollar piece simultaneously, adjusts the primary selector R and the secondary selector It so that when subsequently the key 3 of series is depressed, the selector R will be inoperative and the selector 11"" will select the 'ejectors E and F." and eliminate or move into an inoperative position the ejector E, whereby the operation oi the actuator (i will deliver three onedollar pieces from the machine.

In respect to the subtractimi of three dollars from seven dollars, the above operation is duplicated except that, when the primary selector 1P" is lowered to its inoperative position by the bell cranks 15, those cranks cooperating with the selector R are elevated so that the last mentioned selector attends to the elimination of the ejector ll from its operative position, the selector It notmov ing from its normal positifin when a key 7 of series I is actuated as above described.

In brief therefore. the denoi'ninational intcrchange involved in the operation of the selectors as just presented. includes essentially an initial selection by the main selector mechanism of change consisting of money of different denominations, a simultaneous adjustment of the primary and secondary selectors of the auxiliary selector mechanism. whereby a denominational interchange oi' the selcclcd coins is efl'cclcd, and a subsequent or final ope'ation of the auxiliary selector mechanism to complete a rc-iuljustinent of the previously and finally selected ejectors so that the latter will dc- ]ivcr the propercomputedamount of change from the machine.

The subtraction of two. four or live dollars from six dollars is accomplished in a manner similar to that dcscribcd in rct'crcnce to three dollars. the shaft 20 having crank arms :21 and 21", (see Fig. l), in addition to the arm 21 for actuating lhe two and four dollar auxiliary selector ll" and R". The bell cranks 1' associated with the live dollar selectors R, are arranged to be actuated by means of the mechanism asarm 32 opcratively connected by a link 33 to the bell crank levers I of the five dollar selector bars R.

Springs 3i are attached to the bell crank levers 6 to hold the keys 9 and w and the selectors enacting therewith in their normal positions. The keys 7) and 'wj are provided with lugs 35 near their lower ends, the latter being adaptedv to be engaged by fingers 3!) on a locking bar 36 coacting with the keys 7) and fingers -l-() of a locking bar 37 coacting with the keys 'w. lVhen the keys and 'w are depressed they will be locked depressed by the respective bars 36 and 37,

and not released until during the reverse.

movement of the actuator G. An arm 41 on said shaft engages and actuates a hook bar 42 that is connected with abell crank lever 42 arranged to engage the bar 36 to lift the latter momentarily. When the bar 36 is lifted, it engages a lug 44 on the bar 37 and simultaneously lifts the latter, the fingers of the respective bars 36 and 37 being thus sinniltaneously disengaged "from depressed keys and w. On the said inward or reverse movement of the arm 41 with the actuator G, the hook bar 42 strikes a trip member and is thus released from opera-' tive engagement with said arm 41.

It IS to be imderstoodthat the ejectors, with or without association with the selector mechanism constitute change delivery means.

The term change receptacles used herein comprehends broadly any change holding means whatever, and such as might be employed for holding paper currency, Whether or not the holder is of a receptacle type. The several mechanisms may be re-arranged to subserve compactness or economy of space, according to what may be best for the special uses to which the machine is'to be put. Furthermore, it is obvious that the series P of lIluIllplllfltlVG devices in cooperation with their selectors, 'torm a nnnuend se- ,lector mechanism, while the series \V of said devices and cooperating selectors constitute suhtrahend selector mechanism.
